Question

If the earth was larger would it have more gravitational pull or heat absorbtion

Answer 1

If the Earth was larger than it is now, but had the same mass inside,
then the forces of gravity on its surface would be smaller than they are now.

If the Earth was larger than it is now, and had MORE mass stuffed inside,
then the gravitational forces on the surface could be larger or smaller than
they are now.  It would depend on how much larger, and how much more
mass inside.

If the Earth was larger than it is now, then it would absorb more heat than
it does now.  But it would also radiate more heat away than it does now.
